I don't recall ever having disagreed with anything I've read in Kraus.
Your posting below disagrees with the information on page 464
of "Antennas for all Applications", 3rd edition.
Of course I reject the notion that there's "phase information in the
standing wave current magnitude".
The standing wave current magnitude is sinusoidal, according
to Kraus. How can you possibly have a sinusoidal wave without
an associated phase angle?
For a 1/2WL thin-wire dipole:
If the source current is 1.0 at 0 deg at t=0, the magnitude
of the standing wave current is cos(X) where X is the number
of degrees from the source. Your statement that there is no
phase information in a cosine function is absolutely false.
In fact, in the above example the arc-cosine of the standing
wave magnitude is the phase angle of the reflected current.
The negative of that angle is the phase angle of the forward
current.
